Hawke's Bay Flood Detention Dams Hazard Zones

The hazard zones for all detention dams have been estimated based on assuming a significant breach were to occur at a time when the reservoir is full (rainy day failure). The hazard zone for Makara #1 dam was determined using a 2-dimensional hydrodynamic model based on ground contours collected via LiDAR. Hazard extents for all other dams were based on contour information (where available), as well as land forms and river forms which may affect the flow as it travels away from the dam.
